1. Introduction to stainless steel oxygen stop valve
Oxygen special stop valve, referred to as oxygen valve. It is a special valve specially suitable for oxygen pipelines. According to the operating characteristics of the oxygen pipeline network and considering the flammable and explosive characteristics of the oxygen medium, the design and manufacture are ensured with safe and reliable operation and superior performance as the design principles, and with reference to the provisions of the "Oxygen Safety Regulations" formulated by the Ministry of Metallurgical Industry of China. Special stop valve for safe operation of oxygen pipeline network.
The main body material of the oxygen special stop valve is stainless steel or copper alloy with excellent flame retardancy. The sealing surface is the body or surfacing. The other internal parts are made of stainless steel or copper alloy. The transmission parts are lubricated with non-flammable grease. And marked with obvious oil-free signs.
In terms of structure, the stainless steel oxygen stop valve has a fully enclosed bracket and a static elimination device. The valve stem is equipped with a dust cap. The special stop valve for oxygen pipelines has been deeply trusted by the oxygen pipeline network of major and medium-sized steel plants, oxygen plants, and petrochemical plants since it was put on the market!
2. Characteristics of the special stop valve for oxygen
For nominal pressure, an internal bypass structure is adopted and an external bypass valve structure is adopted. Its purpose is to reduce the pressure difference between the front and back of the valve to avoid high flow rates, high flushing and high temperatures, thereby ensuring the safe operation of the oxygen pipeline network and also reducing the operating torque.
, Oxygen stainless steel stop valve medium flow direction, the medium flows from the bottom of the valve disc to the top of the valve disc (that is, low in and high out). The medium flows from the side of the valve disc into the bottom (high in and low out). For the valve, the medium flows in high and low out. On the one hand, the flow direction of the internal bypass valve meets the structural needs of the internal bypass valve; on the other hand, the closing force of the valve is greatly reduced due to the effect of the medium pressure.
The stainless steel oxygen stop valve is equipped with an electrostatic safety device to avoid Sparks are generated due to static electricity.
Compared with ordinary stop valves, stainless steel stop valves, the bracket part of the stainless steel oxygen stop valve for oxygen pipelines adopts a fully enclosed structure, and the protective cover on the bracket can be opened when the packing is pressed. , plays the role of preventing oil and dust. There are obvious oil-free signs.
All parts are strictly degreased.
